Booting has been interrupted several times

What does F01018 mean?

The module's booting process has been repeatedly interrupted, potentially due to power loss, a CPU crash, or invalid user data. Upon this fault, the module will revert to factory settings. Persistent interruptions indicate an underlying hardware or configuration issue, risking loss of custom parameters and operational instability.

• Unstable or intermittent 24VDC control power supply to the module, causing repeated power cycles during boot-up.
• Corrupted firmware or user application data on the module preventing successful initialization.
• Hardware defect on the module's main circuit board (e.g., CPU, memory, or bootloader components).
• A persistent short circuit or overload condition on an auxiliary output of the module that prevents full system initialization.
• Faulty or incompatible removable memory card (e.g., SD card) inserted into the module, interfering with the boot process.

Click steps to track your progress.

1. 1

   Measure the 24VDC control power supply at the module's input terminals with a multimeter; verify stability and correct voltage level.

2. 2

   Remove any removable memory cards (e.g., SD card) from the module and attempt to boot; if it boots, the card may be corrupt.

3. 3

   Disconnect any communication cables (e.g., Ethernet, PROFIBUS, DRIVE-CLiQ) and external loads from auxiliary outputs, then attempt to boot.

4. 4

   If a firmware update was recently performed, attempt to re-flash the firmware to ensure its integrity, following manufacturer instructions.

5. 5

   If the module reverts to factory settings, re-download a known good parameter set from a backup to restore configuration.

6. 6

   If the fault persists, consider replacing the module, as it may have a hardware defect that prevents successful booting.
